了解掺入了橡胶颗粒的再生沥青混合料的抗车辙性能,对今后使用再生沥青混合料是具有积极作用的。以往的事实证明使用再生沥青是极具经济性和环保性的,同时它还能有效地增加沥青混合料的抗车辙能力;而橡胶沥青的使用也被证实它能有效地改善混合料的路用性能,譬如抗车辙性能等,应用于全国各地以至于世界各地的热拌橡胶沥青混合料就是使用橡胶沥青的成功典范。本研究是通过一系列室内试验,对橡胶沥青混合料的抗车辙性能进行研究分析,这些试验包括掺入了2类橡胶、4种橡胶用量和3种尺寸橡胶颗粒的情况。试验表明在热拌沥青中掺入一定量的再生沥青和橡胶颗粒能有效地改善混合料的抗车辙性能。
Understanding the rutting resistance of a recycled asphalt mixture with rubber particles has a positive effect on the future use of a recycled asphalt mixture. It has been proven in the past that the use of recycled bitumen is very economical and environmentally friendly. At the same time, it can effectively increase the anti-rutting ability of asphalt mixtures. The use of rubber bitumen has also been proved to be effective in improving the road mix Performance, such as anti-rutting performance, applied to all parts of the country and around the world hot rubber asphalt mixture is the successful example of the use of rubber asphalt. In this study, a series of laboratory tests were conducted to analyze the anti-rut performance of rubber asphalt mixtures. These tests include the incorporation of two types of rubber, four kinds of rubber and three kinds of rubber particles. Experiments show that mixing hot asphalt with a certain amount of recycled asphalt and rubber particles can effectively improve the anti-rutting performance of the mixture.
